To all whom t may concern:

Be it known that I, FRANCISCO VIEIEA DE BEM, a subject of the King ofPortugal, residing at Gloucester, in the county of Essex and State ofMassachusetts, have invented certain new and useful Improvements inIndicating- Charts for Marine Signaling-Codes; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improved combined compass-card andcode-instruction card or chart for marine signaling systems; and thepresent application is a division of my application for Letters Patentfor an improved marine signaling code, Serial No. 659,034, iiledNovember 18, 1897, and allowed March 15, 1898.

The primary object of this invention is to provide a simple andconvenient chart or card adaptable for use either as a code-instructioncard or compass-card, whereby the signalcode may be under the inspectionof the steersman or master of the vessel, who can determine at one andthe same time the course of the vessel and the proper signals to soundto indicate said course.

The invention is illustrated in the accompanying drawings, in whichFigure l is a diagrammatic View of the compass chart or card. Fig.v 2 isa View showing a progressive group `of marks representing thecode-signals; and Fig. 3, a view of a reference-card explanatory of thecode.

For ready reference and for the purpose of instruction the code-signalmarks and their deiinitions may be printed upon a card A, as shown inFig. 3, each code character V representing two almost continuous longblasts or full tones and each character l following thereafter a shortblast or semitone, which is sounded after a proper interval of rest. Thecode-signal marks and the points indicated thereby, as shown. in Fig. 3,are as follows:

W, VVVv Six continuous blasts, last prolonged.

-NN W, VVVVI. Eight continuous, one separate prolonged blast. Anchoredvessel, VVVVV, ten continuous blasts.

Port and starboard, usual code-signals.

cipal intermediate divisions thereof, NE, SE, SW, and NW, while thesequence characters 1, represent short blasts or semitones followingeach full blast or combination of full blasts, indicate the minorintermediate divisions NNE, ENE, ESE, SSE, SSW, WSW, VN W, and NNW. Ashort tick or extension on the terminal character, such as l", denotes aprolongation of the last note.

My improved compass-card and indicatingchart B is shown in Fig. l. Thischart or card representation of an anchored vessel and alongside thesame the proper code-signal to be sounded thereby. card may in practicetake the place of the ordinary compass-card in order that the code maybe under the inspection of the steersman or master of the vessel.

For a fuller explanation of l the signalingcode reference is to be hadto my former application hereinbefore mentioned. Itis to be bears uponits face the point characters enumerated above and the rhumb-pointdivisions a, arranged in two concentric circles b c at the outer edgethereof, as usual. At the center of the card is a circular space CZ andbetween the same and circles c three concentric circular spaces e f g.Extending from the central circle is astar-shaped figure having fourmain points h radiating to the cardinal-point characters and fourauxiliary points 7?. radiating to the principal intermediate points anddividing the chart into eightv parts, as shown. Radial division-lines iin the circular space g between the star-points and leading to the eightminor compass-points further divide the compass into sixteen parts. Thecode-signal marks are arranged in the circular space e, and in thecircular space f adjacent thereto are numerals from 2 to 9, indicatingthe number of blasts each code-mark represents. The said code marks andnumerals are arranged in two progressive sets at diametrically op positesides ot' the compass-cards, one set extending from N to SSE on the onehand and the other set from S to NNV on the other hand, thecorresponding diametrically opposite points on the compass beingrepresented by the Same marks, and from this it will be seen that asystematic and exceedingly simple arrangement of the code-signal marksis provided. For the purpose of instruction the circular space g maybear opposite the compass-points the representations of vessels pursuingvarious courses, and in the central circular space I have shown theunderstood that the particular code characters herein shown are notessential to the present invention and that dierent characters may beemployed to represent the sound-signals without departing from thespirit and scope of the invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

An improved compass chart orcard bearing adjacent toits outer edge thecardinal points and intermediate rhumb-points, a series of fourconcentric circles between said points and the center of the card, astar-shaped figure having main points extending from the innermostcircle to the cardinal points and auxiliary points extending to theprincipal intermediate rhumb-points, a series of radial division-linesin the outmost circle leading to the minor intermediate compass-points,and series of code marks and numerals designating said points arrangedin the two intermediate circles, said series consisting of two sets ofequivalent marks and numerals each extending around one-half of thecompass, and the same mark and its designating-numeral in each casebeing placed adjacent to and representing the diametrically oppositepoints on each side of said compass, substantially as described. g

In testimony whereof I afix my signature in presence of two witnesses.
